For a lot of people, if their grandparent or grandparents friends have certain names, it makes those names feel completely unusable because of the connection they have to an old person. I could never use the name Irene because I grew up knowing a crusty old smoker with a dozen cats named Irene. I recognize that it can be a pretty name, but the connection kills it for me.

Don't worry about bad reactions from one or two people. If everybody hates them, then maybe rethink.

But I hope you have a lot of years to consider before the choice is necessary.
